Installation Of The Remote Condensing Unit; Setup; Line Set - Hoshizaki KMS-1122MLH Instruction Manual

E. Installation of the Remote Condensing Unit
• Installation must be performed by properly trained and EPA-certified service
personnel.
• Power supply and ground wire to the icemaker are supplied from the remote
condensing unit. For details, see "II.F. Electrical Connection."

1. Setup

1) Secure the legs to the remote condensing
unit with the 16 bolts and nuts provided.
See Fig. 7.
2) The legs have 8 mounting holes. Secure
the legs with 8 bolts (not included).

2. Line Set

• The icemaker, line set, and remote condensing unit must contain the same type
of refrigerant. Mixing of refrigerants will result in improper operation and possible
damage to the refrigeration system.
• The maximum line set length is 66' (20 m). No refrigerant charge adjustment is
necessary.
• The maximum vertical distance between the remote condensing unit and icemaker
is 33' (10 m) above or 10' (3 m) below the icemaker. These distances are measured
fitting to fitting. See Fig. 8.
• If the vertical distance between the remote condensing unit and the icemaker
is greater than 20' (6 m) (not to exceed 33' (10 m)), an "S" oil-trap (5/8" OD
copper tubing) must be installed in the suction line. The "S" oil-trap must be
located halfway between the icemaker and remote condensing unit. This ensures
sufficient oil return to the compressor.
